Peninsular beargrass is a rare, dioecious shrub-like plant from dry chaparral and coastal sage scrub in Southern California, growing with a rosette of long, narrow leaves. It is a fire-follower that blooms prolifically after wildfire and needs protection from habitat loss.

About
Nolina cismontana, the chaparral beargrass, chaparral nolina, California beargrass, Peninsular beargrass, or peninsular nolina, is a rare species of flowering plant of the Peninsular and Transverse Ranges in California. It is endemic to (known from) only four counties in Southern California: Los Angeles, Orange, San Diego and Ventura Counties. There are perhaps 15 to 17 occurrences in existence, with a total population estimated between 10,000 and 20,000.
This species, previously classified as a subspecies of Nolina parryi, was elevated to species status in 1995. The type specimen is from Trabuco Canyon. The two species differ in morphology as well as habitat and ecology.
Where it grows
Nolina cismontana occurs in coastal mountain ranges in dry chaparral and coastal sage scrub habitat on rocky sandstone and gabbro substrates. By contrast, N. parryi is more often found in woodlands on granite soils.
